GEOCOGEN Project – Part 4

The GEOCOGEN Project

Point number 1 – how do we get the energy to the surface?

This is the crux of the project – it is the part of the project that was not feasible when Kurt Brunnschweiler invented it 30 years ago. Today’s tunneling equipment is fully capable of building a shaft or tunnel as much as 15-20 kilometres deep – that is around 10-15 miles deep. Switzerland has some of the premier tunneling operators in the world, and they are drilling tunnels this long – albeit mostly horizontally – through the Alps and in many other locations around the world. For these tunnels, large diameter vertical ventilation shafts are also necessary, and some of these are 2 kilometres (6600 feet) long and more.

The objective is to make the tunnel up to 10 meters (33 feet) in diameter, shore up the walls to prevent cave-ins, and run piping from the surface level to the bottom of the tunnel where the water will be heated to supercritical temperature and will rise back to the surface under pressure. The process will be what is called a thermosiphon, but on a grand scale. A thermosiphon is where there is a heat source at the bottom of a hairpin of tubing, and the lighter heated water (or steam) rises by itself in the exit (outlet) side because it is less dense and it is replaced by more dense, cold water coming down the other (inlet) side. Looking at is another way, the column of water weighs more than the column of steam, and so it tries to displace it. A daily example is the percolator coffee maker.

The supercritical steam (don’t worry about what “supercritical” means here – just think of it as being REALLY HOT! – far above 100°C) will be used to drive conventional steam turbines, similar to those being used in powerhouses today, coupled to electrical generators. The systems will be sized to create around one GigaWatt of electrical energy – that’s 1’000 MegaWatts – enough to power a city of around half a million inhabitants, depending upon the degree of electrical consumption per capita.

In addition to the electricity generated, there is enough heat available that the entire city could be heated by steam and/or hot water from the GEOCOGEN plant in a district heating concept, with enough left over for many greenhouses and hot water spas.

To be continued …

GEOCOGEN Project – Part 4

Hi there!

As Practical Greenology teaches us, we all should live green and save money at the same time, and we can too. Kermit the Frog was wrong when he said, “It ain’t easy being green.” It really is easy, and highly effective too, if you know how. This article provides you with six essential steps you can start taking today to live green and save money.

1. Turn your heater thermostats down one or two degrees in winter, and turn your air conditioning thermostats up one or two degrees in summer. If we all did this, the combined difference would be phenomenal. We’d still feel warm in winter and cool in summer, so learn how to live green and save money with your heating and cooling appliances.
2. The other appliance that needs your attention is your washing machine. Start washing your clothes in cold water. Modern powders work just as efficiently in cold water as hot. Most of the energy that goes into a clothes wash is in heating up the water, so you will save on electricity, live green and save money too.
3. Speaking of washing machines – including dishwashers this time – don’t run the machine until you have a full load. The machines are designed to work best and most efficiently under full load conditions, and you will heat more-or-less the same amount of water for a partial load as for a full load. And as far as dishwashers are concerned, rinsing the dishes before you put them into the machine is a waste of water – probably hot water. The modern devices work just as well with dirty plates as clean ones.
4. When your clothes are nice and clean out of the washer, don’t throw them into the dryer. Unless it’s pouring rain, hang them out to air dry. It’s what your grandmother did, and she managed just fine. She may have liked having a dryer, but they weren’t around back then, so she just had to live green and save money. You can too!
5. Compact fluorescent light bulbs are a dream come true for anyone who wants to live green and save money. They burn just 25% of the electricity that a standard light bulb burns, and they can last up to 10 times longer. Change your old bulbs today!
6. Try to consume a little less of everything, from electricity, to gas in the car, to the food you eat. Take time to write out a shopping list, and stick to it. If you feel the impulse to buy something you don’t really need, get into the habit of waiting 24 hours, then review it. The chances are you either won’t want it any more, or you will have forgotten about it.

It’s easy to live green and save money. You just have to give it some thought. Get into a routine that works and before you know it, you will find yourself in the situation where you live green and save money every day.
